Introduction

The following rules apply throughout this Service Manual:1. Each chapter contains sections explaining the purpose of specific functions and the relationship between electrical and mechanical systems with refer-

ence to the timing of operation.In the diagrams, represents the path of mechanical drive; where a signal name accompanies the symbol , the arrow indicates thedirection of the electric signal.The expression "turn on the power" means flipping on the power switch, closing the front door, and closing the delivery unit door, which results insupplying the machine with power.

2. In the digital circuits, '1'is used to indicate that the voltage level of a given signal is "High", while '0' is used to indicate "Low".(The voltage value, how-ever, differs from circuit to circuit.) In addition, the asterisk (*) as in "DRMD*" indicates that the DRMD signal goes on when '0'.In practically all cases, the internal mechanisms of a microprocessor cannot be checked in the field. Therefore, the operations of the microprocessorsused in the machines are not discussed: they are explained in terms of from sensors to the input of the DC controller PCB and from the output of theDC controller PCB to the loads.

The descriptions in this Service Manual are subject to change without notice for product improvement or other purposes, and major changes will be com-municated in the form of Service Information bulletins.All service persons are expected to have a good understanding of the contents of this Service Manual and all relevant Service Information bulletins and beable to identify and isolate faults in the machine."

3.3.2 Detecting the Presence/Absence of an Original0013-3469

The presence/absence of an original in the original tray is detected by the original sensor (S6).When an original is placed on the original tray, the light from the light-emitting side of the original sensor is blocked, causing the light-receiving side of the originalsensor to send the original detection signal (DTS) to the ADF controller PCB, which in response turns on the Original Set indicator.

Item Description Sensor used (notation)

Presence/absence of an original Identifies the presence/absence of an original on the original tray. Original sensor (S6)

Original size 1 Identifies the size of the original placed in the original tray (as to beinglarge-size or small-size).

3.3.3 Original Size Detection 10013-3470

In original size detection 1, the original trailing edge sensor is used (S7), which is designed to identify the original in the original tray as being small-size or large-size.When the original covers the original trailing edge sensor, the light from the LED of the original trailing edge sensor is reflected by the original to hit the phototran-sistor, at which time the DADF identifies the original as being large-size.The DADF sends original size data (small-size or large-size) to the copier, which uses the data to determine the point at which the scanner is stopped for streamreading.

Small size: A5, A4, B5, STMT, LTR

Large-size: A4R, B5R, A3, B4, LTRR, LGL, 279.4X431.8mm (11"X17")

3.3.4 Original Size Detection 20013-3471

A. OutlineIn original size detection 2, the original width detecting switch (SW301) and the registration roller clock sensor (PI5) are used to identify a default size.The original width detecting switch is designed to find out the width of originals. As many as five contact plates (SSW0 through 4) are in contact with the originalwidth detecting switch, operating in keeping with the slide guide. The state (ON or OFF) of each contact plate is communicated to the ADF controller PCB, whichuses the input to determine the width of the original.The following table shows the states of the contact plates in relation to default sizes; the states other than those indicated are assumed to indicate the presence of anoriginal which is not of a default size.

The registration roller clock sensor (PI5) is used to measure the length of originals with reference to the revolutions made by the clock plate mounted to the slaveroller of the registration roller. Based on the revolutions of the lock plate, the ADF controller PCB identifies the length of the original in question (in feeding direc-tion).

F-3-17The DADF uses the data on the width and the length of the original obtained by original detection 2 to identify a default size, and sends the result to the copier. Inresponse, the copier selects the appropriate copy paper size to suit the identified size of the original.The following tables show the default sizes in relation to the sizes detected by the DADF:

Be sure to adjust the slide guide to suit the original size when making copies.Otherwise, the original is likely to move askew.

C. Slide Guide Positioning MemberThe rail of the slide guide is provided with notches to make sure that the slide guide stops to suit a specific default original size. Some of these points representingdiffering paper sizes, however, are close enough to allow the slide guide to be set at the wrong point.To prevent wrong positioning of the slide guide, the DADF comes with two types of slide guide positioning members; when fitted correctly, the positioning mem-bers will make sure that the slide guide will stop at the correct point.

The DADF's separation assembly is equipped with a separation pressure switching mechanism which enables switching between two settings (low or high).The separation pressure may be switched by operating the separation pressure lever located in front of the separation assembly. When the lever is operated, theposition of the separation belt moves up or down to change the amount of overlap in relation to the feeding roller, thereby varying the separation pressure.

A separation fault (delay) is identified if the separation sensor does not detect an original a specific period of time after the separation motor has started to rotate.

F-3-28Both separation sensor and skew sensor are used to find out whether an original is moving askew. These two sensors are arranged in a single row in front-reardirection. An original is identified as moving askew if a discrepancy in timing is detected when it moves past these sensors. If the discrepancy is an equivalent of10 mm, the DADF will assume that the original is moving askew, at which point it stops its operation to protect the original and causes the copier to indicate a jammessage.

3.4.5 Controlling the Pickup Motor (M3)0013-3482

The following is a diagram of the circuit used to control the pickup motor (M3).The pickup motor is a 4-phase stepping motor, and has the following mechanisms:- turning on/off the motor- controlling the direction of motor rotation- holding the motor at rest

F-3-30[1] ADF controller PCBM3: pickup motor

The CPU (IC18) sends phase control signals (PICKA, PICKB, PICKA*, PICKB*) to the motor driver (IC31). In response, the motor driver controls the outputtiming of the pulse signals accordingly, switching over the direction of motor rotation.PICKI0/PICKI1 is a current setup signal, and its variation (combination) enables a switch-over among 4 steps (from 0 % to 100 %). PICKSTBY is a motor standbysignal, and is used to turn off the motor drive circuit, during which time no phase signal is sent to the motor.

F-3-31[1] ADF controller PCB[2] Current detection circuitM4: separation motorMI2: separation motor clock sensor

When the CPU sends the motor rotation speed signal (SPPWM), the separation motor (M4) starts to rotate in a specific direction. The separation motor clock sensor(PI2) sends the separation motor rotation speed signal (SPCLK) to IC17 (speed control IC). In response, IC17 compares the arriving rotation speed signal againstthe speed reference signal (SEPCLKREF) from the CPU, and sends the result as the speed control signal (SPMFV) to the CPU. Using the arriving speed controlsignal, the CPU varies the rotation speed signal. LED3 goes on when the motor rotation speed is within a specific range, while going off if out of the range. Thecurrent detection circuit monitors the current flowing in the separation motor; when the level of the current exceeds a specific value, it sends the separation motorstop signal (SPLIM) to stop the motor. The CPU identifies a fault in the separation motor if the separation motor stop signal continues, indicating an error code(E405) on the host machine's display.

3.7 Detecting Jams

3.7.1 Overview 0013-3519

The machine checks for jams using the following sensors. The CPU on the ADF controller PCB runs a check at such times as programmed in advance, and detectsthe presence/absence of a jam in relation to the presence/absence of paper over a specific sensor.Upon detection of a jam, the machine communicates the fact to the host machine, which in turn indicates the fact in service mode in the form of a code. A checkmay also be made with reference to the indicator (DSP1) of the machine's ADF control PCB.
